NEWSPAPERS editors were threatened with prosecution under the Official Secrets Act last night if they published details of a conversation between Tony Blair and George Bush in which the President is alleged to have suggested bombing al-Jazeera, the Arab news network. Lord Goldsmith, the Attorney-General, informed newspapers editors including that of The Times that “publication of a document that has been unlawfully disclosed by a Crown servant could be in breach of Section 5 of the Official Secrets Act.”
